..."The Guardian will now publish the Mauna Loa carbon count, the global benchmark, on the weather page of the paper every day.

“Levels of carbon dioxide in the atmosphere have risen so dramatically, and including a measure of that in our daily weather report is symbolic of what human activity is doing to our climate. People need reminding that the climate crisis is no longer a future problem – we need to tackle it now, and every day matters.”

Last time CO2 levels were this high, there were trees at the South Pole

While weather changes daily, climate changes over years and decades. So alongside the daily carbon count, we will publish the level in previous years for comparison, as well as the pre-industrial baseline of 280ppm, and the level seen as manageable in the long term of 350ppm.

Year-on-year comparisons are important because each year there is a natural rise and fall of CO2 levels, rather like the planet breathing. Trees and plants absorb carbon and release oxygen as they grow, lowering atmospheric CO2."...(more)
